EDWIN HEALD, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN FLOAT-VALVES FOR CISTERNS.

Specification forming part of Letters Patent No. 57,321, dated August 21, 1866.

To all whom it may concern: I

Be it known that I, EDWIN HEALD, of the city of Washington, District of Columbia, have invented an Improved Float and Valve Oombined for Regulating the Flow of Water in Gisterns; and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

Figure 1 represents the float and valve combined, and showing how it may be attached to a water-pipe and operated in a cistern of water. Fig. 2 shows a sectional view.

The nature of my invention consists in a circular or globular float, with a piston, guides, valve, and double-screw collar or cylinder, so as to be connected with a water-pipe for the purpose of regulating the flow of water in cisterns.

A represents the float, that may be made of any material and any shape. It is attached to a rod or piston, B, with a round button or valve, 0, at the upper end of the piston B. The piston operates in two circular guides, D D, between two stays, E E, that are connected with the cylinder G.

water in the cistern presses the float A upward, and thus shuts off the flow of water.

When the waterdischarges from the cistern the float lowers with it, and the valve 0 falls down upon the ofl'sets J J, and the water again flows through the cylinders H and G, and into the cistern, refilling the cistern with the quantity of water required and regulating the quantity.

What I claim as my invention, and desire to secure by Letters Patent, is-

The construction and combination of the float A, piston B, guides D D, valve 0, and double screw-cylinder H, forming the valveseat 0, all as herein described, and for the purposes set forth.

EDWIN HEALD.
